Unified Command

Whenever there is an incident involving more than one agency with jurisdiction, a joint command arrangement, called the Unified Command, is implemented. The Unified Command for the Repsol Q2 Pad Gas and Mud Release consists of the U.S. Environmental Protection Agency, the Alaska Department of Environmental Conservation, Repsol E&P USA, and the North Slope Borough.

Incident Description

mapRepsol contractor Nabors Drilling was drilling an exploratory well when the drill penetrated a shallow gas pocket at a depth of 2,523 feet, resulting in a gas kick.

The gas kick drove drilling mud out of the well and through the gas diverter onto the ice pad and adjacent snow-covered tundra.

The gas diverter is a pipe that extends approximately 75 feet from the drilling rig toward the south edge of the pad. Additional mud was pumped into the well in an attempt to control it, but that mud was also forced out by the gas.

Incident Update

February 29, 2012 -- Response crews continue 24-hour operations to steam thaw and remove drilling mud from the drilling rig in order to access the essential drilling rig components needed for the well-kill operation.

Temperatures remain extremely cold with a -71°F wind chill, so outside equipment continues to be shut down. However, work inside the rig continues.

Lights and electrical heat are energized in parts of the rig. Crews are continuing the cleaning and drying of the rig's power components, a critical step in the eventual re-start of the rig.

The re-start of the rig is one in a series of steps in the progression needed for completion of the well-kill operation. However, due to the need for a very methodical and careful cleaning and drying of the rig's power components, the time of the re-start cannot be determined at this time.

Repsol reports that 232 barrels (9,744 gallons) of liquids (thawed drilling mud and water) were shipped offsite for disposal in the past day, bringing the total to 1,666 barrels (69,972 gallons) of liquids that have been manifested and shipped offsite. Much of the liquid being collected is condensed water from the steam used to thaw the frozen drilling mud. Due to the extremely cold temperatures, no solid wastes were manifested or shipped offsite yesterday.
